Eyeglasses



UNITED STATES JOHN L. BORSCH, OF PHILADELPHIA, PENNSYLVANIA.

EYEGLASSES.

SPECIFICATION forming part of Letters Patent No. 410,233, dated September 3, 1889.

Application led March 23, 1889. Serial No. 304,482- (No model.)

To all whom it may concern.-

`Be it known that I, JOHN L. BORSCH, a citizen of the United`4 States, residing at Philadelphia in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Eyeglasses, of which the following is a specification, reference bein'g had therein to the accompanying drawings.

This improvement relates to that class of eyeglasses provided with nose-pieces distinct from the frame; and the invention consists in the peculiar construction, arrangement, and combination of parts hereinafterk more particularly described, and then deinitely pointed out in the claims.

In the accompanying drawings, -Figurel represents a front elevation o f a pair of eyeglasses provided With my improvement. Fig. 2 is a vertical central section of the same; Fig. 3, a front elevation of a modification; Fig. 4, a vertical central section of the same. Figs. 5, 6, and 7 are front elevations of other forms ofnose-pieces detached.

All of the above are on a larger scale than the originals from Which they are made, the better to show the small parts.

Referring noW to the details of construc-` tion,A represents the frames,which are made in any suitable or desirable ,form or material, to which is preferably attached the bar B, having atits free end a carrier O, preferably of spring metal, each of whose ends carries a nose-piece D, of rubber, cork, or other suitable material, Which may be attached in any desired Way; but I prefer to attach them by means of thin plates E, fastened in any desired Way to the ends of the carrier and having their sides turned up, so as to clampthe the rubberor cork between said turned-up sides.

In the modification shown in Figs. 3 and 4 there is no bar B, the carrier being fastened directly to the frame. In Fig. 5 there is a cross-bar Z9 attached to the end of bar B, and to the ends of .this cross-bar are attached coiled springs, the free ends 'of which carry the nose-pieces.

In Fig. 6 there is also a cross-bar attached itis at the center to the main bar B, behind which is a spring, substantially the same as carrier C in the other figures. To the opposite ends,

Vof the spring are attached pins c, each of which carries a nose-piece.

In Fig. 7 there is another form of cross-bar, which is provided with ears b', in which the nose-pieces are pivoted.

I do not intend to limit myself, except Where especially claimed, either to spring, bendable, or rigid metal for the parts carrying the nose-pieces, as either may be used, at the Will of the manufacturer. In some cases the wearer may prefer thatV these parts be of spring metal,while others may prefer that the metal may be capable of being bent to suit the nose and depend upon the bridge for the' spring.

It is evident from the above that my inven-` tion may be varied in `many Ways Without departing from the main feature of my invention, whichV consists in duplex or double nosepieces-that is to say, nose-pieces having two separate bearings on the sides of the nose.

The carrier may be attached to the bar B in any convenient manner; butI prefer to attach it by a pivotor screw` for then the carrier may be adjusted at any convenient angle to the lens to suit the Wearers nose.

The carrier may, if preferred, be made in one piece With the bar, as shown in Fig. 7. What I claim as new is 1. EyeglassesA having duplex nose-pieces attached to a carrier having a central connection with the eyeglasses and adjustable at right angles to the lenses, substantially as described. 1

2. The combination, with a pair of eyeglasses, of a bar B, a nose-piece carrier adjustably connected at its center With said bar B and carrying a nose-piece at each end, substantially as described.

3. The combination, with a pair of eyeglasses, of a bar B, a nose-piece carrier adjustably connected to said bar B and having nose-pieces flexibly connected to each of its ends, substantially as described.

4. The combination, with a pair of eyeglasses, of a bar B,a spring attached thereto,

and a nose-pies@ at each end of the spring, in presence of two wit-messes,thsQOth' dayof substantially as described. March, 1889.

.5. The combination, with L pair of eyeglasses, of aber B, a carrier @and nose-pieces JOHN L' BORSCH' 5 D, pvotally attached to each end of the czu- Vtnesses:

rielg, substantially as described. FRANK R. STEVENSON,
